LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Oct. 31, 1911.

To all whom it may concern:

Be it known that I, JOHN G. MAGIN, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Loose-Leaf Binders, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to loose leaf binders and an object thereof is to provide a simple and inexpensive construction of the type in which the leaves are adapted to be shifted from supporting or impaling pins gr projections onto a suitable transfer mem- Another object of the invention is to pro-, vide for connecting the leaves to their impaling pins or projections in such a manner that their removal from the said pins, or projections may be eifected without friction.

To these and other ends the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a perspective view of the invention embodied in a binder having a cover; Fig. 2 is a section through the binder with the retaining member in operative position; Fig. 3 is a section showing the retaining member removed and the position of a portion of the leaves during the removing operation. Fig. 4 is a transverse section through the supporting member, and Fig. 5 is a sectional view of another embodiment in which the transfer member has but one pin or projection.

In carrying out the invention there may be employed a supporting member prefer-- ably in the form of a thin strip 1 of metal having impaling pins or projections 2 extending from one side thereof, and a strip 1 of inverted U-shape in cross section fitted over the strip 1 and having lugs 1 depending from the inner side thereof to cooperate with the upper surface of the strip 1. Gooperating with the impaling pins or projections is a retaining member comprising preferably an elongated box shaped member 3 having openings 4 in one side thereof to receive the ends of the pins 2, the retaining member being held to the pins in any suitable manncr. In this instance, a .slide or locking bar 5 operates longitudinally Within the box shaped member and has two shoulders 6 which engage beneath shoulders 7 near the ends of the impaling projections, a

spring 8 tending to move the bar to locking position, and a portion 9 projecting from one end of the retaining member and serving as an operating portion by which the bar is moved from looking position.

If desired, the binder may be arranged on a suitablecover comprising, in this instance, a backing 10 hinged at opposite edges at 10 to the retaining and to the supporting member, and two leaves 11 one hinged at 11 to the retaining member and the other hinged at. 11 to the supporting member.

The loose leaves 12 may have perforations 13 near one edge, preferably, in the form of slots whose lengths are alined, the distance between the proximate ends of the slots beingequal to the distance between the proximate faces of the impaling projections 2, so that the said faces are engaged by the ends of the slots to prevent lateral movement of the leaves, and, at the same time, when leaves are lifted by placing the hand underneath the same between the two impaling pins, said leaves move transversely of the pins, as shown in Fig. 3, to prevent all friction which would retard the removal of the leaves.

Another feature of this invention.is the provision of a simple and inexpensive means to which the leaves are transferred on being removed from the impaling pins or projections. This means comprises, preferably, a plate or bar 14: having one or more projections 15 extending from one side thereof. In thiscmbodiment shown in Figs. 1 to 3 two such projections are employed, whereas, in the embodiment shown in Fig. 5 only one of such projections is provided, the latter however being wide and flat to prevent the leaves turning thereon.

The transfer projection or projections cooperate with the support below the lower projecting portions of the impaling or supporting projections, so that no additional projecting portions are provided on the supporting member to interfere with the removal of the leaves from the impaling pins, and, in addition, the transfer means is rendered simple and inexpensive to manufacture. In the present instance, both strips of the supportingmember are provided with perforations 16 which receive the ends of the transfer projections, said ends preferably being reduced in order to provide shoulders 17 which cooperate with the upper surface of the supporting member and limit the movement of the latter in the perforations 16. By having two spaced strips 1 and 1 each provided with a perforation, I can secure greater supporting surface for the transfer pins with a light structure. Of course, the leaves 12 are provided with open ings 18 through which the transfer projections or pins 15 are passed downwardly, so that the plate 14 will cooperate with the uppermost leaf 12. It will be noted that the transfer member lies between the projections 2 so that it cannot be separated from the supporting member 1 while the retaining bar" 5 is in retaining position.

To remove a leaf from the binder, the locking bar 5 is moved to disengage the retaining member from the projections 2. The leaves, above the leaf to be removed, are then lifted upwardly by passing the hand underneath them between the two impaling pins, thus lifting the transfer member with the removed leaves. The latter are now inverted onto a suitable support and arethus held in proper relation until they are refitted onto the impaling pins.

From theforegoing it will be seen that there has been provided a loose leaf binder in which the transfer member is of simple construction and engages the supporting member in such a manner that no projecting parts, which would interfere with the removal of the insertion of a leaf, are provided on the supporting member. The impaling projections on the supporting mem-' her are so arranged with relation to slots in the loose leaves that the removal of the latter may be effected without frictionally engaging the projections.

What I claim as my invention and desire to secure by Letters Patent, is:

1. The combination with a supporting member and an impaling projection extending therefrom, of a transfer member having a transfer projection engaging the supporting member below the inner end of the projecting portion of the impaling projection in such a manner that the transfer member is thereby supported in an upright position by its projection alone.

2. The combination with a supportingmcmber and an impaling projection extending therefrom, of a transfer member having a transfer projection engaging the supporting member below the inner end of the 'irojecting portion of the impaling projection in such a manner that the transfer member is thereby supported in an upright position by its projection alone, and a retaining member cooperating with the impaling projection near the free end thereof and root/sea lying in a position to prevent the removal of the transfer member from the supporting member.

3. The combination with a supporting member provided with an opening and an impaling projectionextending from said member to one side of the opening, of a transfer member having a projection fitting in said opening at such a depth that the transfer member is thereby supported on the supporting member by its projection alone. r

at. The combination with a supporting member provided with an opening and an impaling'projection extending from said member, of a transfer member having a transfer projection fitting in said opening at such a depth that the transfer member is thereby supported on the supporting member by its projection alone, and a retaining member cooperating with the impaling projection near the free end thereof and lying in a position to prevent the withdrawal of the transfer projection from the supporting member. r

5. The combination with a supporting member provided with at least two impaling projections, of a transfer member having a transfer pin cooperating with the supporting member below the upper surface of the latter in such a manner that the transfer member is thereby supported in an upright position by its transfer pin alone and a retaining device cooperating with the impaling projections near their free ends and lying in a position to prevent the separation of the transfer member from the supporting member.

6. The combination with a supporting member provided with an opening in one face thereof and an impaling projection extending from said member, of a transfer member having a transfer pin fitting in said openingat such a depth that the transfer member is thereby supported on the supporting member by its transfer pin alone and provided with a shoulder to limit the movement of the pin in the opening.

7. The combination with a supporting member provided with a plurality of openings and impaling projections extending from said member on opposite sides of the openings, of a transfer member having a plurality of projections provided with reduced ends fitting the openings of the supporting member at such a depth that the transfer member is thereby supported on the supporting member by its projections alone, and a retaining bar having devices for interlocking with the impaling projection, and lying in a position to prevent the removal of the transfer member from the supporting member.

8. The combination with a supporting member formed from two spaced strips provided with alined openings, and impaling pins each projecting from said supporting member to one side of the opening, of a transfer member having a transfer .pin thereon adapted to fit in said alined openings.

9. A loose leaf binder comprising a strip, provided with an opening, impaling projections extending from one side of the strip,

an inverted U-shaped member fitted over the strip and provided with an opening alined With the opening in the strip,-and a transfer member having a projection provided with a reduced end fitting in the alined openings.

10. The combination with a supporting member and a pair of impaling projections extending therefrom, of a plurality of loose sheets each having a pair of alined slots, the length of each of which is greater than the width of the impaling projection fitting therethrough so that the latter may move laterally therein, and the distance between the proximate ends of the slots being equal to the distance between the proximate faces of the projections.
